Dr. Jeremy Stewart

Lab director


Dr. Jeremy Stewart has devoted his career to understanding the development and progression of mental health disorders in adolescents and young adults. Using a multi-modal approach grounded in clinical psychological science and neuroscience methods, he aims to uncover new insights regarding the cognitive, emotional, and behavioural processes that contribute to psychopathology in youth. Jeremy strives to translate his findings to enhance assessment and interventions for young people coping with mental illness, and ultimately, to improve well-being.

Jeremy’s most recent work is geared to understanding the onset and worsening of suicidal thoughts and behaviours, particularly. Suicide science faces many challenges. Among them is the fact that most people who think seriously about suicide will not make attempts, and most strong predictors of suicidal thoughts (e.g., depression) tell us little about who is most likely to act on these thoughts. Consequently, guided by a developmental psychopathology framework, Jeremy’s research aims to identify risk factors that cut across diagnostic boundaries that may contribute to the escalation from suicidal thoughts to actions. As this transition is a pivotal target for suicide prevention, Jeremy hopes that his findings will contribute to curbing unnecessary and preventable loss of life.

Presently, Jeremy is appointed as an Assistant Professor in the Department of Psychology at Queen’s University in Kingston, Ontario. His research team—the Queen’s Emotions and Risky Behaviours in Youth (QuERBY) Laboratory—is a dynamic group of junior scientists committed to improving the safety and well-being of Canadian youth through leading-edge research; local (e.g., campus), provincial, and national knowledge translation; and advocacy. Overall, Jeremy is privileged to have such an inclusive, professional, and hard-working lab who share his enthusiasm for psychological science!


Genevieve Bianchini

undergraduate thesis student

Genny is an undergraduate honours thesis student in the QuERBY lab, and she is investigating self-destructive behaviours in youth that are associated with life stress. Her research interests include improving treatment models for adolescence risky behaviour and better understanding the risk factors for suicide ideation in teens."

Lauren Harper

undergraduate thesis student

Lauren is a fourth-year undergraduate student working toward a Bachelor of Arts in Psychology. She is very excited to be completing her honours thesis in the QuERBY Lab and is looking forward to working with the research team to better understand risky behaviours in youth. For her thesis project, Lauren is designing a novel coding system of free written responses to better understand the role of rejection sensitivity in adolescent suicide attempts.



Megan Rowe


I am a third year Psychology major and work as a research assistant in the QuERBY lab. My responsibilities include both rating and writing LEDS (Life Events and Difficulties Schedule) vignettes. I am also currently completing a PSYC 570 (Directed Laboratory) project in the lab under the supervision of Dr. Stewart. My project takes a LEDS approach to studying individuals’ (romantic) relationship outcomes, with specific focus on the influence of Attachment Anxiety and associated behaviours.
